摘　　要：针对虚拟现实技术中虚拟场景的生成及仿真问题,将场景中的实体位置状态及其基元间的连接关系统一用关节描述;通过建立场景连接图来描述场景结构模型,并采用关节驱动基元的方式来进行场景的更新操作,从而提出一种面向连接的关节驱动型虚拟场景的动态建模与实时仿真方法。在此基础上,开发通用的虚拟场景可视化软件平台,并通过测试验证提出的方法可以有效提高场景的建模与仿真处理效率。Focusing on the virtual scene modeling and simulation problems in virtual reality technology,the entities＇ positions and status along with the connection among their basic elements are described uniformly with joint;by constructing scene connection graphs,the scene architecture model is described;additionally by way of joint-driven entity elements,the scene updating operation is executed.Hence a connection-oriented joint-driven virtual scene dynamic modeling and real-time simulation technology is proposed.It is taken as the basis on which to develop a universal virtual scene visualization software platform.Moreover,by tests it is proven that the proposed method can effectively promote the processing efficiency on modeling and simulation.
